Some of Hollywood’s brightest stars threw a charity auction at Sotheby’s last night – with a few things they’d found in the attic – and raised more than $400,000 to fight AIDS in Africa.

Only 15 items went under the hammer, including the 52-inch sword used by Mel Gibson in “Braveheart,” which went for $170,000.

“I haven’t sold a sword for that amount of money in my life!” said auctioneer Jamie Niven, who ran a good-humored ship before a SRO audience.

Other high bids were $74,000 for the bullwhip used by Harrison Ford in all three of the “Indiana Jones” movies, donated by Steven Spielberg; $54,000 for Liam Neeson’s light-saber in “Star Wars: Episode 1,” donated by George Lucas; and $50,000 for a Faberge-framed photo of Audrey Hepburn dressed in her Liza Doolittle getup from “My Fair Lady.”

The auction concludes today when the online version wraps up.

The top bid for an online item as of last night was $4,100 for the sexy-to-the-bone outfit worn by Halle Berry in “The X-Men.”

“We’ve found a lot of bidding comes right at the end,” said an unfazed Patty Fox, a Sotheby’s spokeswoman.

The lowest successful bid was $1,000 for what the catalog called “a private and personal birthday phone call” from Michael Jackson.

Proceeds will be used to combat mother-to-child AIDS transmission in Zambia, Zimbabwe and Ivory Coast where nearly 1.5 million children have been orphaned.

Some of 77 items still on the block at http://www.sothebys.com are leather cowboy boots from Elizabeth Taylor and a pair of “Rocky” boxing gloves signed by Sylvester Stallone.
